Test Retest Reliability

Abstract Background The sit-to-stand test (STS) is a representative motor test. In most of STS, the time taken to complete the test was used as its score, and its quality of motion has not been focused. In the present study, we measured the lower trunk angular velocity using gyro sensor during STS and computed the angular velocity-based indices (AV-index). We investigated its test-retest reliability and concurrent validity. Method Seventy-eight older people in community-dwelling were participated. Basic-health-related-information and the previous one-year fall-history were obtained by a questionnaire. As motor-function tests, One Leg Standing test (OLS), 3 minutes walking test (3MWT), Timed Up and Go test (TUG) were performed. Additionally, Modify Five-Times-STS was performed twice, the lower trunk angular velocity during the tests were measured using gyro sensor. From the obtained-signal waveforms in the sagittal plane (SP), root mean square (RMS) and coefficient of auto correlation (AC), the mean impact at sitting timing (STS impact) in Modify Five-Times-STS were computed. The intra-class correlation coefficient (ICC) was calculated for the test-retest reliability of the AV-indices. The coefficients of Pearson’s correlation were computed between AV-indices and the Five-Times-STS score, and scores of motor-function tests. Result The ICC of STS impact and RMS in SP were 0.85. The ICC of the other AV-index were lower than 0.5. The RMS in SP was significantly associated with OLS (r = 0.24), and 3MWT (r = 0.36), TUG (r = −0.32). Additionally, the STS impact was significantly associated with 3MWT (r = 0.54). Conclusions The test-retest reliability of two AV-index (STS impact and RMS in SP) is good. The concurrent validity of AV-index is partly confirmed.

Test Retest Reliability

AbstractIntroduction. Tests of upper-extremity motor function used for people following a stroke have been described, but reliability and validity (psychometric properties) of measurements obtained with these tests have not been consistently established. This investigation was performed: (1) to review literature relative to upper-extremity motor function testing during rehabilitation following a stroke, (2) to develop selection criteria for identifying these tests in the literature, and (3) to rate the tests relative to their psychometric properties. Method. Literature searches were done using 2 databases. Reports of 4 psychometric properties were sought: interrater reliability, test-retest reliability, convergent validity or concurrent validity, and predictive validity. Results. Nine tests met the inclusion criteria of having psychometric properties reported in the literature. No test had evidence for all 4 psychometric properties. Only the Nine-Hole Peg Test was supported by 3 out of 4 properties. Most tests had 2 properties supported. Concurrent validity or convergent validity was most frequently described; test-retest reliability was least frequently described. Conclusions. More complete psychometric support is needed for upper-extremity motor function tests applied following a stroke. The absence of psychometric support, however, does not mean that a test has no value. Clinicians are cautioned not to generalize psychometric evidence.

Test Retest Reliability

Background. Children with cerebral palsy often suffer from a lack of balance compared with typically developing children. Because balance capacity is relevant to functional activities, reliable and valid functional balance measures are crucial for the pediatric clinical setting. Objective. This study examined the reliability and validity of 3 functional balance measures. Methods. Thirty children aged 60 to 142 months with Gross Motor Function Classification System (GMFCS) levels of I to IV were recruited. For test-retest reliability, the same physical therapist administered the Functional Reach Test (FRT), Berg Balance Scale (BBS), and Timed Up and Go (TUG) twice. For interrater reliability, the testing processes were video recorded and later scored by another therapist. For convergent validity, children with cerebral palsy received the Gross Motor Function Measures (GMFM), walking speed, and 10-second sit-to-stand test within 1 week and the results evaluated. Results. The 3 functional balance measures had excellent test-retest reliability (intraclass correlation coefficient [ICC] >0.95) and interrater reliability (ICC = 0.98-1.00). With regard to convergent validity, the BBS and the TUG were highly correlated with GMFM total score, walking speed, and the 10-second sit-to-stand test. The discriminate validity indicates that the FRT can distinguish children with cerebral palsy with different GMFCS levels, whereas the BBS total score and TUG failed to distinguish between children with cerebral palsy with GMFCS levels of I and II. Conclusion. The 3 functional balance measures are simple, valid, and reliable for examining children with cerebral palsy and are thus suitable for clinical practice.

Test Retest Reliability

Functional independence in adults is conditioned by lower limb muscle strength. Thus, it seems important to assess lower limb strength using reliable and easy to reproduce measurements. The purpose of this study was to conduct a systematic review and meta-analysis to collect studies that examined the test-retest reliability of the Five Times Sit to Stand Test (FTSST) in adults. The search was conducted in PubMed, Web of Science, and Scopus databases, including all studies published up to 28 December 2020. To be included, studies had to include relative reliability scores (ICC) and maximum torque or standard error of measurements (SEM) of FTSST. A total of 693 studies were initially identified, but only 8 met the eligibility criteria and were included in the meta-analysis, covering a total of 14 groups with 400 participants. Relative inter-rater reliability results (ICC = 0.937, p < 0.001, n = 400) revealed excellent reliability of FTSST to assess sitting and standing performance, lower limbs strength and balance control. Conclusion: The Five Times Sit to Stand Test is a highly reliable tool for assessing lower limbs strength, balance control, and mobility in both healthy adults and those with pathologies.

Background: Simple field tests such as the Timed Up and Go test (TUG) and 30 s Chair Stand test are commonly used to evaluate physical function in the elderly, providing crude outcome measures. Using an automatic chronometer, it is possible to obtain additional kinematic parameters that may lead to obtaining extra information and drawing further conclusions. However, there is a lack of studies that evaluate the test-retest reliability of these parameters, which may help to judge and interpret changes caused by an intervention or differences between populations. Thus, the aim of this study was to evaluate the test-retest reliability of the Timed Up and Go test (TUG) and 30 s Chair Stand test in healthy older adults. Methods: A total of 99 healthy older adults participated in this cross-sectional study. The TUG and the 30 s Chair Stand test were performed five times and twice, respectively, using an automatic chronometer. The sit-to-stand-to-sit cycle from the 30 s Chair Stand test was divided into two phases. Results: Overall, reliability for the 30 s Chair Stand test was good for almost each variable (intraclass correlation coefficient (ICC) >0.70). Furthermore, the use of an automatic chronometer improved the reliability for the TUG (ICC >0.86 for a manual chronometer and ICC >0.88 for an automatic chronometer). Conclusions: The TUG and the 30 s Chair Stand test are reliable in older adults. The use of an automatic chronometer in the TUG is strongly recommended as it increased the reliability of the test. This device enables researchers to obtain relevant and reliable data from the 30 s Chair Stand test, such as the duration of the sit-to-stand-to-sit cycles and phases.

AbstractObjectivesIt is essential to have simple, reliable and valid tests to measure children’s functional capacity in schools or medical practice. The 1-min sit-to-stand test (STS) is a quick fitness test requiring little equipment or space that is increasingly used in both healthy populations and those with chronic disease. We aimed to provide age and sex-specific reference values of STS in healthy children and adolescents and to evaluate its short-term reliability and construct validity.Design, setting and participantsCross-sectional random sample from 6 public schools and 1 science fair in central Europe. Overall, 587 healthy participants aged 5-16 years were recruited and divided into age groups of 3 years each.Outcomes1-minute STS. To evaluate short-term reliability, some children performed the STS twice. To evaluate construct validity, some children also performed a standing long jump (SLJ) and a maximal incremental exercise test.ResultsData from 547 5-16 year old youth were finally included in the analyses. The median number of repetitions in 1 minute in males (females) ranged from 55 [95% CI 38 to 72] (53 [35 to 76]) in 14-16 year-olds to 59 [41 to 77] (60 [38 to 77]) in 8-10 year-olds. Children who repeated STS showed a learning effect of on average 4.8 repetitions more than the first test (95% limits of agreement −6.7 to 16.4). Moderate correlations were observed between the STS and the SLJ (r = 0.48) and the maximal exercise test (r = 0.43).ConclusionsThe reported STS reference values can be used to interpret STS test performance in children and adolescents. The STS appears to have good test-retest reliability, but a learning effect of about 10%. The association of STS with other measures of physical fitness should be further explored in a larger study and technical standards for its conduct are needed.Strengths and Limitations of this StudyLarge sample size (N = 547)Reference values according to sex and age group (5-7, 8-10, 11-13 and 14-16)Evaluation of test-retest reliability and construct validityConvenience not population-based sampleNot all outcomes have been measured on each participant

he most frequently employed versions of the sit-to-stand test (STST) are the 5 times STSΤ and the 30 seconds STST. However, it is not known whether a variation with different number of repetitions or time could be more appropriate for older adults. The objective of this study was to investigate the reliability of STST at different time points and number of repetitions. The test was performed in 33 older adults (73±6.1 years) for 40 seconds. The participants performed the procedure twice with a day interval between the sessions. The test was video-taped and the data were processed by two examiners. The highest test-retest reliability was found for the 4th (ICC=0.73, SEM=1.48, SDD=1.68), 5th (ICC=0.76, SEM=1.73, SDD=1.97) and 6th repetition (ICC=0.78, SEM=1.78, SDD=2.03). The inter-rater reliability was excellent independently of the number of trials (ICC>0.9). The correlation of the time at the 4th and 6th repetition with the time at the traditionally selected 5th repetition was excellent (r>0.9). The termination of the STST at the 4th repetition seems to provide equally reliable and valid estimations with the termination at the 5th repetition. Future studies should examine a 4 times STST since the reduction of the number of repetitions may be less tiring and safer for older adults.
